Go green with our eco pet food bags! Keep food items fresh with all the benefits of an eco sustainable package. These flexible pouches are made from 100% compostable materials and offer a high barrier. Our eco pet food bags are made from the polylactic acid (PLA) of plants and include a laminated protective ALOX coating. Here are the details: PLA (Polylactic Acid) is a bioplastic material made from renewable resources such as corn and sugar. It is a sustainable product and is compostable in industrial composting facilities. It is a great material to use in packaging as it is food safe and relatively inexpensive. ALOX (Aluminium Oxide) Coating is a clear barrier coating and when applied to flexible plastic film can achieve high oxygen and moisture barrier properties. ALOX is compostable and when used with a PLA film will create a high barrier, compostable package.
